Ahead of the "Gilmore Girls" reunion at ATX Television Festival, one of the greatest fictionalcover bands of all time reunited as Keiko Agena (Lane), Todd Lowe (Zach) and John Cabrera (Brian) reformed Hep Alien during a secret show at the San Jose Hotel.

The group has kept in touch over the years and this isn't the first time they've played since "Gilmore Girls" ended in 2007. Back in October, they staged a one-night only show (a photo of which reveals Agena rocking out in full Lane form).

Fans following Cabrera's twitter would know the gang has been practicing for their triumphant return this weekend. In late April, he posted a photo of the three (sans Sebastian Bach and the long lost Adam Brody).

Going away to college is tough. Just ask anyone who's done it. It's even tougher when your mom is your best friend, so this episode is obviously an emotional (and great) one.
